I'm giving RiscOS a try on mine. Interesting stuff...
I finally tried out the RiscOS on mine. It's amazingly zippy compared to the linux versions for the Pi.
Haven't quite got the hang of the mouse yet, but the font rendering is amazing!
Like the built in editor, even if there is no syntax highlighting for python
Cons: Netsurf crashes if you have any bangs(!) in passwords.
That's it so far. Overall, the RiscOS is a much nicer fit for the pi than raspbian IMHO.
EDIT: I have the 'old' 256 meg version.
